Not Applicable
Completed
Conditions
Atopic Dermatitis
Interventions
Other: Topical Ointment with L. reuteri
Other: Topical Ointment without L. reuteri
Registration Number
NCT03632174
Lead Sponsor
BioGaia AB
Brief Summary

The study consists in the application of 2 investigational products (one group per investigational product) under normal conditions of use, in adult participants with Atopic Dermatitis.

It is carried out on cosmetic products, with the aim to further confirm safety of these products

Detailed Description

Probiotics are live micro-organisms which when administered in adequate amounts can exert a health benefit on the host. This health-promoting effects of Lactobacillus reuteri have been extensively studied in the gastrointestinal tract but it is clear that other areas are also interesting for the use of probiotics.

Atopic Dermatitis is a relapsing inflammatory skin disease appearing on persons with a genetic predisposition of allergic pathology. AD generally starts in childhood, however in some cases can continue into adult hood, in at least 10% of cases. AD can effect a persons quality of life and in the chronic stage it can present with dry skin and lichenification.

Research has shown that probiotics have an antimicrobial, anti-inflammatory and barrier function effect, and could therefore be used on subjects with Atopic Dermatitis to relieve and protect.

Primary Outcome Measures
NameTimeMethod
Appraisal of Cutaneous acceptability of the investigational products by dermatologist investigator4 weeks

Cutaneous acceptability is assessed on the basis of clinical examination of the skin for physical signs (erythema, oedema, dryness) linked to the use of the investigational product and also evaluation the functional signs (prickling, tightness, heating)

Secondary Outcome Measures
NameTimeMethod
Change in Local SCORAD indexbaseline, at 4, and 8 weeks

Change evaluated by the dermatologist investigator at each visit, on the recurrent lesion (defined area) and control area selected at baseline

Change in SCORAD index over 8 week periodbaseline, at 4 and 8 weeks

Clinical evaluation by the dermatologist investigator to assess change in skin conditions to each parameter of "SCORing Atopic Dermatitis" (SCORAD) (erythema, edema, xerosis) and participant symptoms: pruritus and sleep quality
